INSTALL PKG-CONFIG FOR MAC OSX

For those who don’t know about pkg-config, it is a tool that help we compile applications and libraries by inserting the correct compiler options.

Now, how can we install pkg-config for Mac OSX ?

Get MacPort
For no headache, install MacPort. It helps a lot when install open source software on the Mac.
Install here http://www.macports.org/install.php. You should choose “pkg” installer for quick use. Remember to select the right Mac version

Install pkg-config
Run Terminal. Cd to where you want to install pkg-config, and enter this

sudo port install pkgconfig

Oops, if you receive this error

port command not found

It is because port is install in /opt/local/bin by default. You should add /opt/local/bin to your PATH

Run Terminal, and enter this for temporary PATH append

export PATH=$PATH:/opt/ local /bin
